            The blend equations determines how a new pixel (the ''source'' color)
            is combined with a pixel already in the framebuffer (the ''destination''
            color).  This function specifies one blend equation for the RGB-color
            components and one blend equation for the alpha component.
        </p><p>
            The blend equations use the source and destination blend factors
            specified by either <a class="citerefentry" href="glBlendFunc"><span class="citerefentry"><span class="refentrytitle">glBlendFunc</span></span></a> or
